West Nile virus accelerates in Europe. Portugal still has no local cases

ZAP Notícias5 September 2026 at 10:40

The West Nile virus is accelerating in Europe, with 15 countries already affected by infections. According to data from the European Centre for Disease Prevention and Control (ECDC), since the start of the virus transmission season, associated with the warmer months, 1,086 human cases have been recorded up to Thursday.

Portugal continues to have no local cases of West Nile virus infection. To date, no locally transmitted infection cases have been identified in Portuguese territory.

In Spain, the situation is more serious, with 88 confirmed cases of the disease. The neighboring country is one of the most affected by the spread of the virus.

The West Nile virus is transmitted through mosquito bites and its transmission season is associated with the warmer months of the year, which explains the increase in cases during the European summer.
